For fleas I use dawn dish soap. Let it sit for just a little while and rinse. God Bless
Personally, I think the best dog shampoo, to get rid of fleas, is a mild and gentle skin care product that contains natural ingredients. I found a natural dog shampoo that is so mild, it can even be used on pregnant and seizure prone dogs. It is an, unscented, dog shampoo that cleanses, conditions and kills fleas immediately upon use!

I put a cap full of clorox in the water with my winnie dog's and watch the flea's fall off..
